Wednesday, November 16, 2022 Oncology phase I trial design and conduct: time for a change - MDICT Guidelines 2022 Recent experience with targeted anticancer drugs and immunotherapies suggest the traditional approach of using the maximal tolerated dose (MTD) is not ideal. Project Optimus recommends optimizing the dosage of oncology drugs to ensure they are both effective and tolerable. MDICT developed practical recommendations for the design and conduct of phase I oncology trials.

Repeatability in all three SUV measurements varied for different lesion locations. Worse repeatability in SUVmean was also associated with higher tumor volumes. Conclusions: Recommendations regarding SUV measurements for assessing minimal detectable changes based on repeatability and reproducibility are proposed and should be applied to differentiate between response categories for FDG-PET-based criteria.
